Abstract
Description
Die Erfindung bezieht sich auf eine photoelektrochemi sche Solarzelle mit einem Farbstoff zur Umwandlung von Photonen in Elektronen sowie mit Mitteln zur Erzeugung eines nutzbaren elektrischen Stroms aus den Elektro nen,, z. B. bekannt aus DE 42 07 659 A1 oder DE 43 06 410 A1 oder US 5,084,365.The invention relates to a photoelectrochemical solar cell with a dye to convert Photons in electrons and with means of generation a usable electric current from the electric nen ,, e.g. B. known from DE 42 07 659 A1 or DE 43 06 410 A1 or US 5,084,365.
Bekannt sind photoelektrochemische Solarzellen oder farbstoffsensibilisierte Solarzellen, die ein elek trisch leitfähiges Substrat aufweisen. Auf dem Substrat ist eine Halbleiterschicht aufgebracht. Auf der Halb leiterschicht ist ein Farbstoff adsorbiert.Photoelectrochemical solar cells or are known dye-sensitized solar cells that an elec trically conductive substrate. On the substrate a semiconductor layer is applied. On the half a dye is adsorbed on the conductor layer.
Nach Anregung des Farbstoffes durch ein Photon wird ein Elektron auf den Halbleiter übertragen. Das im Inneren des Halbleiters herrschende elektrische Feld sorgt für den weiteren Transport des Elektrons. Die auf dem Farbstoff zurückgebliebene positive Ladung wird auf ei nen Redoxmediator übertragen. Der Redoxmediator befin det sich in einer die Zelle ausfüllenden Lösung. Vom Redoxmediator wird die positive Ladung an die Gegen elektrode weitergeleitet. Mit diesem letzten Elektro nentransfer wird der Redoxmediator in den reduzierten Zustand zurückversetzt und der elektrische Stromkreis geschlossen. Auf diese Weise sind die Elektronen in ei nen nutzbaren Strom umgewandelt worden, da der Strom nun technische elektrische Geräte wie z. B. elektroni sche Bauteile, Elektromotoren usw. betreiben kann.After excitation of the dye by a photon, a Transfer electron to the semiconductor. That inside prevailing electrical field of the semiconductor ensures the further transport of the electron. The one on the Dye remaining positive charge is on egg transmit a redox mediator. The redox mediator is is in a solution filling the cell. From Redox mediator will transfer the positive charge to the counter electrode passed. With that last electro The redox mediator is transferred to the reduced Condition reset and the electrical circuit closed. In this way the electrons are in egg usable electricity has been converted because the electricity now technical electrical devices such. B. electronics cal components, electric motors, etc. can operate.
Der Farbstoff sollte stabil sein, einen guten Wirkungs grad bezüglich der Umwandlung von Photonen in Elektro nen und großes Adsorptionsvermögen an der Halbleiter schicht aufweisen.The dye should be stable, have a good effect degree regarding the conversion of photons into electro and large adsorption capacity on the semiconductor have layer.
Um die Halbleiterschicht mit dem Farbstoff zu beschich ten, wird dieser in eine ethanolische Lösung gebracht, in welche die Halbleiterschicht (Adsorbens) getaucht wird. Nach einigen Stunden in dieser Lösung ist die Halbleiterschicht mit einer Monolage des gewählten Farbstoffs bedeckt.To coat the semiconductor layer with the dye is placed in an ethanolic solution, in which the semiconductor layer (adsorbent) is immersed becomes. After a few hours in this solution it is Semiconductor layer with a monolayer of the selected Dye covered.
Als Lösungsmittel für den Farbstoff wird bevorzugt Ethanol verwendet, da dieses leicht und rückstandsfrei verdampft sowie relativ wasserfrei erhältlich ist. Es ist verhältnismäßig kostengünstig, ungiftig und zer stört nicht die Halbleiterschicht.Preferred as the solvent for the dye Ethanol is used because it is light and residue-free evaporated and is available relatively anhydrous. It is relatively inexpensive, non-toxic and zer does not interfere with the semiconductor layer.
Es ist aus US 5,084,365 bekannt, die Farbstoffe RuL(Ru(bPY)₂(CN)₂)₂, RuL₂(NCS)₂, RuL₃ bei einer photo elektrochemischen Zelle vorzusehen (L = 2,2′-bipyridyl- 4,4′-dicarboxylat).It is known from US 5,084,365, the dyes RuL (Ru (bPY) ₂ (CN) ₂) ₂, RuL₂ (NCS) ₂, RuL₃ in a photo electrochemical cell (L = 2,2′-bipyridyl- 4,4'-dicarboxylate).
Nachteilhaft sind die verwendeten Rutheniumkomplexe sehr teuer und kommerziell schwer oder nicht erhält lich. Sie sind kaum in Ethanol löslich. Bei längerer Aufbewahrung fallen diese Komplexe in einer solchen Lö sung aus. Sie müssen dann durch Behandlung im Ultra schallbad wieder in Lösung gebracht werden.The ruthenium complexes used are disadvantageous very expensive and commercially difficult or not obtainable Lich. They are hardly soluble in ethanol. With longer ones Storage these complexes fall into such a Lö solution. You then have to go through treatment at the Ultra sound bath are brought back into solution.
Gleichzeitig sind die oben genannten Farbstoffe in ethanolischer Lösung schon bei geringstem Lichteinfall instabil, d. h. sie zersetzen sich innerhalb weniger Wo chen.At the same time, the above dyes are in ethanol solution even with the slightest light unstable, d. H. they decompose within a few weeks chen.
Nur wenn die Farbstoffkomplexe an Titandioxid adsor biert sind und von dem erwähnten Redoxmediator um schlossen werden, sind sie länger stabil.Only if the dye complexes adsorbed on titanium dioxide are and from the redox mediator mentioned closed, they are stable longer.
Die vorgenannten Eigenschaften erschweren die Handha bung der Farbstoffe und die Herstellung von farb stoffsensibilisierten Solarzellen.The aforementioned properties make the handha difficult exercise of dyes and the production of color fabric-sensitized solar cells.
Aufgabe der Erfindung ist die Schaffung einer photo elektrochemischen Zelle mit einem stabilen, kommerziell preiswert erhältlichen, leicht handhabbaren Farbstoff mit hohem Wirkungsgrad bei der Konversion von Photonen in Elektronen.The object of the invention is to create a photo electrochemical cell with a stable, commercial inexpensive, easy-to-use dye with high efficiency in the conversion of photons in electrons.
Die Aufgabe wird mit einer photoelektrochemischen Zelle mit den Merkmalen des Hauptanspruchs gelöst. Bevorzugte Ausführungsformen ergeben sich aus den rückbezogenen Ansprüchen.The task is done with a photoelectrochemical cell solved with the features of the main claim. Preferred Embodiments result from the related Claims.

Fig. 1 bis 4 zeigen die Strukturformeln der Farb stoffe. Die relative Ausgangsleistung ist ein Maß für den Wirkungsgrad des Farbstoffes bei der Umwandlung von Photonen in Strom. Figs. 1 to 4 show the structural formulas of the dyestuffs. The relative output power is a measure of the efficiency of the dye in converting photons into electricity.
Die vorgenannten Farbstoffe sind kommerziell leicht er hältlich, kostengünstig, und sie werden bei stickstoff gepumpten Farbstofflasern eingesetzt. Sie sind in ethanolischer Lösung oder in Dioxan leicht löslich. Sie verhielten sich 2 Jahre lang und länger bei voller so larer Einstrahlung stabil.The aforementioned dyes are commercially light Stable, inexpensive, and they are made with nitrogen pumped dye lasers used. They are in ethanol solution or easily soluble in dioxane. she behaved like this for 2 years and longer at full Larger radiation stable.
Die Aufbringung der Farbstoffe auf den Halbleiter ge schieht in der eingangs beschrieben Weise. Aufgrund ih rer Lichtunempfindlichkeit konnten sie jedoch sehr viel leichter verarbeitet werden. Ihre Leistungsfähigkeit, ihr Adsorptionsvermögen sowie ihre Langzeitstabilität innerhalb einer farbstoffsensibilisierten Solarzelle erwies sich als gut.The application of the dyes to the semiconductor ge happens in the manner described above. Because of her However, they were very capable of light insensitivity be processed more easily. Your performance, their adsorption capacity and their long-term stability inside a dye-sensitized solar cell turned out to be good.
Für eine farbstoffsensibilisierte Solarzelle geeignete, zusammen mit den erfindungsgemäßen Farbstoffen einsetz bare Substrate weisen insbesondere eine Rutilstruktur, wie z. B. die Oxide ZrO₂, VO₂, NbO₂, CrO₂, MoO₂, WO₂, MnO₂, RuO₂, OsO₂, IrO₂, GeO₂, SnO₂, PbO₂, TeO₂, die Flu oride MnF₂, FeF₂, CoF₂, NiF₂, PdF₂, ZnF₂ und MgF₂ oder eine Anatasstruktur auf.Suitable for a dye-sensitized solar cell use together with the dyes of the invention bare substrates in particular have a rutile structure, such as B. the oxides ZrO₂, VO₂, NbO₂, CrO₂, MoO₂, WO₂, MnO₂, RuO₂, OsO₂, IrO₂, GeO₂, SnO₂, PbO₂, TeO₂, the flu oride MnF₂, FeF₂, CoF₂, NiF₂, PdF₂, ZnF₂ and MgF₂ or an anatase structure.
